Tyres are one of the most important safety components of your vehicle, yet they are often the most neglected. Many UK drivers unknowingly drive with worn tyres, assuming “they’ll last a bit longer.” But is it actually illegal to drive with worn tyres in the UK? And if so, what are the fines, penalty points, and legal consequences?

In this guide, we’ll break down UK tyre laws, explain how worn is too worn, and show you how services like Tyre Vortex can help you stay safe and legal on the road.

UK Tyre Law: What Does the Law Say?

Yes — it is illegal to drive with worn tyres in the UK.

According to UK law, all tyres fitted to a vehicle must meet the minimum legal tread depth and be in a roadworthy condition. These rules apply to:

• Cars

• Vans

• Motorcycles

• Light commercial vehicles

The law exists for one main reason: safety. Worn tyres dramatically reduce grip, increase stopping distance, and raise the risk of skidding, especially in wet conditions — which, let’s be honest, is common on UK roads.

What Is the Legal Minimum Tyre Tread Depth in the UK?

The legal minimum tread depth for cars and vans in the UK is:

1.6mm across the central three-quarters of the tyre, around the entire circumference

Anything below this is considered illegal.

Most tyres come with tread wear indicators (TWIs) built into the grooves. If the tread is level with these indicators, your tyre is already at or below the legal limit.

Pro tip: If you’re unsure, Tyre Vortex offers quick tyre checks and replacements — including mobile and emergency services contact.

What Happens If You Drive with Illegal Tyres?

Driving with worn or illegal tyres can lead to serious penalties.

 Fines & Penalty Points

For each illegal tyre, you could face:

• £2,500 fine

• 3 penalty points

That means if all four tyres are illegal:

•  Up to £10,000 in fines

• 12 penalty points (enough for a driving ban)

And that’s just the legal side.

Can Worn Tyres Invalidate Your Insurance?

Yes — absolutely.

If you’re involved in an accident and your tyres are found to be below the legal limit:

• Your insurer may refuse to pay out

• You could be held fully liable for damages

• Claims for injuries could come directly to you

Even if the accident wasn’t your fault, illegal tyres can still weaken your case.

How Dangerous Are Worn Tyres Really?

Very.

Here’s what worn tyres can cause:

• Longer braking distances

• Aquaplaning in wet weather

• Loss of control on corners

• Higher risk of blowouts

• Poor grip in cold conditions

In wet weather, tyres worn below 1.6mm can increase stopping distance by up to 50%.

This is why replacing tyres early isn’t just legal compliance — it’s common sense.

How Often Should You Check Your Tyres?

You should check your tyres:

• Once a month

• Before long journeys

• Before MOT tests

• After hitting potholes or kerbs

Check for:

• Tread depth

• Cracks or bulges

• Uneven wear

• Low tyre pressure

If you don’t have the tools or time, Tyre Vortex provides fast tyre inspections and same-day replacements across the UK.

MOT Failure: Can Worn Tyres Fail an MOT?

Yes. Tyres are a key MOT check item.

Your vehicle will fail its MOT if:

• Tread depth is below 1.6mm

• Tyres are damaged, cracked, or bulging

• Tyres are incorrectly fitted or mismatched

A failed MOT means:

• You cannot legally drive the vehicle (except to a repair centre)

• You’ll need immediate tyre replacement

Are Part-Worn Tyres Legal in the UK?

Part-worn tyres can be legal, but only if they meet strict requirements:

• Minimum 2mm tread depth (higher than standard tyres)

• Clearly marked as “PART-WORN”

• No internal or external damage

• Passed a pressure test

Cheap, unregulated part-worn tyres are risky and often illegal. If you’re considering them, make sure they’re supplied by a trusted tyre provider like Tyre Vortex.

Emergency Situations: What If Your Tyre Becomes Illegal Suddenly?

Tyres can wear out faster than expected — especially with:

• Long motorway driving

• Heavy loads

• Poor wheel alignment

If you realise your tyres are illegal or unsafe:
